A long-range laser rangefinder is capable of measuring distance up to 20 km; mounted on a tripod with an angular mount. The resulting system also provides azimuth and elevation measurements. A laser rangefinder , also known as a laser telemeter , is a rangefinder that uses a laser beam to determine the distance to an object.
10 meters – wavelength of the highest shortwave radio frequency, 30 MHz; 10.2 meters – length of the Panzer VIII Maus, the world's largest tank; 12 meters – height of the Newby-McMahon Building, the world's littlest skyscraper; 23 meters – height of Luxor Obelisk, located in the Place de la Concorde, Paris, France

A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.
The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...
The "chart" actually consists of a pair of charts: one, the individuals chart, displays the individual measured values; the other, the moving range chart, displays the difference from one point to the next.
Essentially, the meter's shunt resistor, used to generate a voltage proportional to load current, is replaced by a much larger value, typically 100 times larger, with protective diodes. Readings of the modified meter have to be divided by the resistance factor (e.g. 100), and maximum measurable power is reduced by the same factor.
Manufacturers have also started to provide range recommendations, updating their websites with small applications that denote the optimum viewing distance as a range of distances. [35] [36] [37] THX in March 2009 added range recommendations to their website. [26] The minimum of the range tends to be the proponent's fixed optimum distance ...
